@F WILMINGTON, DELAWARE, A CORPORATION OF DELAWARE PRINTING APPARATUSApplication filed December 22, 1930. Serial No. 503,3?2.

Copending applications of mine show, describe and claim'a method ofprinting, wherein a flexible galley is employed-in which line printingmembers are mounted in one or more columns, this galley being adapted tobe stored flat, and, for use, wrapped about the rotary drum of aprinting machine. The present invention is concerned with means forapplying such flexible galley to the drum' and for holding it tightlythereon in use.

To the. above ends, 1 form the galley near one or both ends with meansto interlock with the drum in such manner as to frictionally retain thatend of the galley in place while the galley is being wrapped around thedrum. My invention also provides effective means for engaging theopposite end of. the galley and drawing it in an arcuate direction totightly seat the galley on the drum My invention is illustrated in thedrawings hereof, and is hereinafter more fully described, and thessential novel features are summarized in the claims.

in the drawings, Fig. 1 is a verticalsection through a rotary printingmachine equipped with my flexible galley and embodying the presentinvention; Fig. 2 is a vertical section through the printing machine,illustrating the galley in the process of being mounted on the drum;Fig. 3 is a longitudinal or axial section through the printing machine;Fig.- 4 is a plan of mymultiple-column galley, removed and flattened;Figs. 5, 6 and 7 are details in cross section through the galley inplanes indicated by the correspondingly numbered lines on Fig. 4.

As illustrated in Figs. 1, 2 and 3, 10 indicates a pair of parallel end;plates of the frame of the printing machine. in this 9 frame is mounteda drive shaft 11 rigidly carrying a pair of skeleton disks 12'and 13 onwhich is mounted a segment 15 having a cylindrical exterior adapted forsupporting the alley. p

The segment .15 may be held on theskeleton drum in any suitable manner.I have shown however, a sleeve 14 concentric of the shaft and mounted onhubs on the end members 12 and 13 of the drum, and I have shown thesegment provided with a suitable. hook 16 adapted to embrace this sleeveand be locked thereto as by a set screw 1'4, Fig. 1.

The flexible galley, designated 20, is adapted to be wrapped around thesegment 15' and held thereon by means hereinafter described. This galleyholds suitable line printing mem-' bers, as for instance the line slugs30. having notches 31 at their ends enabling them to be held by suitableslats 21 on the alley.

When the galley carrying the line printing members is mounted on thesegment, as illustrated in Fig; '1, the printing face of the printingmembers may coact with a platen 40 mounted on a shaft 41' carried by theend plates 10 to enable printing in the usual manner. In printing, anysuitable means may be employed forv inking the type faces. ll haveillustrated in Fig. 1, an inked ribbon 45 mounted on spools dficarriedwithin the drum, this ribbon intermediately overlying the faces of theprinting members. I intend being held slidably on the base plate, as bytongues 23, cut out of the base plate and turned upwardly and passedthrough slots in the strips and slats. The construction in thisparticular may be in accordance with copending application No. 445,501filed April 18th, 1930, by myself and Peter M. Colquhoun. The purpose ofmounting the slats and filler strips slidably is to enable the wholeconstruction to ilex readily, so that the galley may be loaded when fiatand stored in that condition and thereafter bent with its form about theprinting segment.

The line printing members which are held in place by projecting beneaththe overhang-' ing galley slats 21 may be low height solid line slugsgrooved at their ends in accordance with a copending application of mineSerial No. 503,87 3 filed concurrently here- I with, or they may becomposite printing members made in accordance with my copendingapplication No. 445,499 filed April 18th, 1930.

" The In any case, a form is made up of one or more columns of suitableline printing members which rest on the base of the galley and are heldat their ends by the slats 21, the column being retained in compactedposition by a suitable follower. I have shown for instance,

a follower 35 (Fig. 4) having tongues engaging opposite sides of theslats 21, this follower being claimed in application No. 445,501heretofore mentione As the loaded flexible galley necessarily hasconsiderable weight and requires some force for its flexing, it isimportant, in mounting it on the drum, that the end first applied to thedrum be eifectively retained other than by a manual pull on the galleywhile the same is being wrapped about the drum, otherwise it isdiificult for one person to apply the galley. To enable this engagementof the end of the galley.withthe drum, I provide a bar 50 secured acrossthe end of the back plate of the galley and then turning across the endof the plate at right angles at 51 and then projectmg beneath the platea short distance at 52. I secure this bar to the back plate by rivets 53which have cylindrical heads extending a material distance beneath theback plate,see particularly Fig. 7 To cooperate with such construction,I make a groove 18 in one end of the segment 15 to receive the hookingflange 52 and I make cylindrical recesses 19 in the face of the segmentnear the end to receive the rivet heads 53. When the galley is .to beplaced on the segment, the latter is preferably temporarily locked inabout the positions shownin Fig. 2. alley is then held in a more or lessuprig t position, and the hook 52 brought into the slot 18. In thismovement, the rivet heads 53 first rest on the segment surface 7 beyondthe recesses 19, but as the book 52 reaches its final position, therivet heads 53 register with the recesses 19 and may be pushed intothem. The wall of the recess nearest the segment end, by engagement withthe rivet heads, efiectively prevents that end of thegalley beingdisengaged from the segment while .the galley is being wrapped aroundthe segment, and until the other end of the galley has been locked inplace.

It will be notice'dfrom Figs. 1 and 2 that the end ofthe segment havingthe notch 18, for receiving the galley hook 52, has an inner portion 48continuing arcuately beyond that 55 .notch. This projecting portionmakes a convenient guide in mounting the galley. I When the segment'isin the position shown in Fig.

" 2, the groove in the end' of the segment is not conveniently visible,but this is unim- 6Q. portant as the operator can simply shove the endof the galley inwardly in a general radial direction beneath the endofthe segmentuntil it abuts the guiding projection 48, then a slightupward pull on' the galley causes .the

hook 52 to come into therecess, after which the projections are ressedinto their recesses as already described Itis convenient to useidentical bars 50 on the opposite ends of the galley, so that the galleymay be mounted either end foremost, as desired. 'To look the free end ofthe galley, I provide means within the printin drum to engage the hook52 at the free en and pull the same in an arcuate direction to draw thegalley tight on the segment and there hold it. Preferably the galley issomewhat longer than the developed length of the segment, so that thewhole locking bar 50 at the free end lies beyond the free end 57 of thesegment, as shown in Fig. 1.

The means for engaging, pulling and holding the free end of the galleyis shown in Figs. 1, 2 and 3. As there shown, it comprises a hookedplate 60 secured to a pair of radial arms 61 rotatably mounted about thesleeve 14 of the drum. These arms are normally pulled away from the end49 of the segment by tension springs 63 anchored at one end to portions64 of the arms opposite the plate 60 and at theirother ends to tensionpins 65 extending from-the sleeve 14. The springs 63 are quite strongand are adapted to move the plate 60 away from the end 49 of the segmentwith suflicient force to draw the engaged galley tightly about thesegment 15 as shown in Fig. 1.

In view of the force of the springs 63 in moving the galley-engagingplate 60, I have provided camming mechanism for readily forcing theplate 60 toward the segment to enable its easy engagement with thegalley, after which, the release of the plate enables the springs to setand hold the galley. The camming mechanism mentioned comprises anoscillating roller 7 O eccentrically mounted in the skeleton members 12and 13 of the drum, provided with a radial operated arm 71 and with atortion spring 72 anchored to the roller and to the drum member 12.

The spring 72 normally retains the arm 71 and the roller in the idleposition shown in Fig. 1. When however, it'is desired to release thesegment which is on the drum, it is only necessary for the operator tograsp the rod '71 and turn it outwardly against the l action of thetortion spring 72 and thus cam the'lqplde 60 toward the segment, asillustrated in ig. 2.

With the segment held by any suitable means in the oblique positionshown in Fig. 2, it is simple to snap the lower end of the galley ontothe retaining device provided by the groove 18 and the recesses '19 andthen bend the galley about the segmentas illustrated in Fig. 2, untilthe bar 50 on the free end of the galley lies over the end of thehookedplate 60 with the flange 52 on this bar 50 opposite the groove 67of this hooked plate. Then the operator releases his holdon the rod 71,which he has been holding dur ing the placing of the segment, and theplate 60 swings away from the segment under the influence of the springs63, so that the notch 67 receives the hook 52 as shown in Fig. 1. As therelease of the hooked plate 60 is completed by the operator allowing therod 71 to be swung into the drum, the force of the spring 63 pulls thegalley arcuately and causes it to seat snugly on the segment 15 andthere remain during the printing operation. To release the galley atanytime, it is only necessary to stop the printing machine with thesegment approximately in the position shown in Fig. 2; for the operatorthen to grasp the rod 71 and swing it outwardly from the drum, thuscamming the plate 60 into position to release the galley which, by itselasticity, tends to unwrap itself from the drum. Then, the operatorhaving stripped the galley, with the exception of the originallyanchored end, from the segment, a slight jerk on the galley will pullthe rivet heads 53 out of 1tlhe recesses 19, thus entirely detaching theg It desirable to provide a cross member at one wend of the galleyforming a stop at the top in the column or columns, against which theline printing members may be compacted by the 'follower 35. My hookedplate 50 of itself forms such stop at the top end of the columns, and,such plates being attached at each end of the galley, either end mayconstitute the top.

There must be" come sliding relation between the retaining slats 21 andthe end plates 50 to enable flexing of the galley. This might beaccomplished by having theslats simply abut the inner edges of thestrips 50 and pull away from them when the galley is flexed; but toprevent any possibility of such free end of the slat bending up andimpressing the paper during the printing, I bend the slats 21 toward thegalley plate adjacent their ends and pass them slidably under the plates50,

as illustrated in Fig.6. To allow aneasy bend of the slat where itpasses from the higher elevation to the lower, I preferably cut notchesin the plates 50 as illustrated in F ig. 4. t

t will be seen that with my means for temporarily locking the initial.end of the galley on the segment and the means'for engaging and drawingon thefinal end, I enable one operator with his two hands to veryreadily mount the galley even though the same is of considerable sizeand weight; and, with equal ease, remove it whenever desired.Furthermore, when the galley is in place, it is effectively held on thedrum during the printing operation. When removed, the galley is simplyflattened and may be stored in that condition for. future use at anytime desired.

The printing form on the galley may be revised by separating it in anydesired region (the follower sliding lengthwise in the galley) and anyobsolete line members skewed and removed, or any new members inserted oradded, as the case may be, in acing one or more recesses in its faceadapted to receive the projections of the galley and means in additionto said projections for anchoring that end of the galley to the printingmember.
